`Be it known that I, 'CARL H. lBrssnnL, a citizen of the United States,andf a-resident of Syracuse, lin th'e'county of Onondaga and vState vvof New York, have Yinvented anew and useful Automatic Switch, of `which the following Vis a specification.

This v`'invention has for its object thesproduction of anv automatic switch which is particularly simple in yconstruction and highly efficient and durable vin use, and it consists in the novel combinations and constructions:hereinafter set forth and claimed.

In describing this invention, Vreference is had :to the accompanying drawings, lin which like characters designate corresponding parts in all the views.

Figures 1 and 2 are plan lviews', partly broken away, of `this switch illustrating, respectively, the positions of the parts when the-switch lis open and closed,fFig. Q being partly brokenaway.

Fig. 2 isa fragmentary sectional view looking `to the left-of the upper partof Fig. 2, the e switch being `shown as open.

Fig. '3 is-a 'sectionen line A-A, Fig. 1.

Fig. 4 yis a detail vie-w of a :part of the circuit ycht`tn,f`=,` ing switch.

Fig. 5 is la diagrammatic `view Villustratingthe electric wiring.

This automatic switch comprises, generarlly, a movable switch member, means for actuating the member inl opposite ldirections tol open and lclose the switch including electro-magnetic means, magnetizable means 'operated lby the electro-magnetic means, :power transmitting means operated by Athe magneti'zable means -and 'connected to the switch Jmember, the electro-magnetic l means being'connected'rinvan operatingxcircuit'having -a reversing switch therein' by which-the energizing' of the electromagnetic means is controlled, whereby theielectroma'gneti'c Ymeans facts 4on the 'magnetizable means inone direction 4to open the Vswitch and in the opposite direction Ato close the switch.

In the illustrated embodiment lof my invention, the electromagnetic means Icomprises `'two magnets, lor a double magnet. The vmagnetizable means `is lan larmature arranged to be acted on bythe magnets; and the power transmitting means yincludes a toggle Aconn'e'cted'to 'the switch member and to a pafrt connected -to the magnetizable means. The joint vofthe toggle preferably moves into or'beyond the dead center line of the toggle when the switch is closed, and a hammer in the form of a magnetizable member is'employe'd to strike a blow to start the operation'ofthe toggle; that is, to carry its joint outl of the dead center line during the initialipart of the opening movement ofthe switch vmember. The windings-of the magnets are designed to be connected in different branches of the operating circuit which is controlled by a manually operated circuit changing switch, and a circuit breaker is operatedby the magnetizable means, the circuit breaker having conductors arranged in the vbranches of the operating circuit and operating to open one branch while the other is closed and to break the circuit through the active magnet after said magnet has performed its work, and to close the branch through the other magnet so that when the circuit changing switch is again operated, the latter magnet will be energized. The magnets are here shown as solenoids and the magnetizable means or armature as a core. Y

1 is the switch member having'conductors 2 movable into and out of engagement with .terminals 3 on a bar or conductor 4f located in the main or feed circuit vto be controlled by the switch member 1, the switch member having suitable contacts 2a similar to the contacts 2, which contacts 2a engage terminals 5 which are similar to the terminals 3 and which are connected to fuse terminals 6 leading yto the load or lighting circuits through fuses 7. The conductor 4- is connected in the main line of the circuit through terminal 8.

The switch member l is, in this embodimentof my invention, movable rectilinearly, and is provided with guides or rods 49 near its opposite ends which slide in suitable openings lformed in the supporting frame 10 of the switch. This frame 10 and the terminals 5, 6 `and conductor 4 are mounted upon a suitable insulating base or board 11, the bar 4 being offset from the base by pillars-as the lpillar 4a Fig. 2a at each end.

12 and 13 are the solenoids, and 14 is a core within the solenoids and common to both of the same. l5 and 16 designate the links of a. toggle which are pivoted together at their inner ends at 17, the outer or lower end of the link 16 being pivoted at 18 to the frame lOand the outer or upper end of the is mounted. Said rod 21 is connected at itsv ends to the links 16 of the toggles by pinand-slot connections, the slots 22 of which are formed in the links and the pins 23 or which are provided on the rod. In order to prevent turning of the rod, it is provided with arms 24 at its opposite ends having bearings 25 which move along laterally eX- tending guide rods 26 provided on the frame 10 and extending parallel to the rod 21. The pins 23 are provided directly upon the hubs of the arms 24.

Obviously, when the solenoid 12 is energized, the core 14 will be pulled to the right, Fig. 1, moving the rod'21 therewith, operating the switch member 1 and closing the switch; and when the solenoid 13 is operated, the core 14 will be pulled to the left returning the toggle from its position sho-wn in Fig. 2 to that shown in Fig. 1, thus opening the switch.

The joint 17 of each toggle is designed to be moved -into or beyond the dead center line of the toggle, that is, a straight line passing through the pivotal points 18 and 19, in order that Vthe switch will be held tightly in its closed position, and the movement of the toggle is limited by a suitable stop as the lower end wall 22a of each slot 22 against which the pin 23 strikes when the toggle is in its extended position.

In order to start the operation of the toggle when it is in its position shown in Fig. 2, means is provided for moving the pins 17 out of the dead center lines of the toggles, said means comprising an electromagnetically operated hammer in the form of a core 27 located within the solenoid 13 and slidable along the rod 21 against a head 28 fixed on the rod. Hence, when the solenoid 13 is energized, when the parts are in their position shown in gure 2, the core 27 is pulled violently to the left and strikes against the head 28, thus operating the toggles to carry their joints out of the dead center lines.

The solenoids 12, 13, or the coils thereof, are designed to be connected in different branches of the operating circuit, in which is located a manually operated reversing or pole changing switch 29 of any suitable construction; and in order that the solenoid made active by the operation of the switch 29 may be rendered inactive when it has performed its work, a circuit breaker is provided having conductors located in the legs 30 and 31 oi the branches in which the solenoids are respectively connected, one of the conductors being in position to close the circuit through one branch when the other conductor is in position to break the circuit through the other branch. Said circuit vbreaker is in the nature of a toggle comprising two levers 32, 33 pivoted between their ends at 34, and 35 to the frame 10, the inner arms of said levers being pivoted together by a pinand-slot joint .36 and the outer arms being connected by a spring 37 which eiiects a quick break operation when the joint 36 passes through the dead center line of the circuit breaker, that is a line passing through the centers 34 and 35.

The armv 33 includes two conductors 38 and 39 which are insulated from each other and movable between terminals 40 and 41 located respectively in the branches 30 and 31 leading to the solenoids 12 and 13.

The circuit breaker is operated by the rod 21, and it is connected thereto by a lost motion connection; and as here shown, the rod 21 is provided with a shoulder 42 which moves between separated shoulders 43 and 44, so that the circuit breaker will not be operated until the rod 21 and toggle links 15 and 16 and switch member 1 have nearly reached the limit of their 'movement in either direction. Vhen the parts are in the position shown in Fig. 1, the circuit breaker is in such position that its conductor 38 closes the branch circuit 30 through the solenoid 12, and hence upon the operating of the switch 29 to close the circuit through the branch 30,v the solenoid will be energized, and the switch arm 1 and the circuit breaker moved to their positions shown in Fig. 2, so that the conductor 39 of the circuit breaker closes the circuit of the branch 31 through the solenoid 13, and the conductor 38 is moved to break the circuit through the branch 3() connected to the solenoid v12. However, the solenoid 13 is not energized as the manually operated switch 29 is in such position that it closes the cir-I cuit through the branch 30 which has just been broken by the switch conductor 38.

During the energizing of the solenoid 12, the core 14 is pulled to the right causing the switch arm 1 to be closed. When it is desired to again reset the parts to their original position, the switch 29 is again operated and closes the branch 31 leading to the solenoid 13, and as this branch has beenzclosed by the conductor 39 during the previous operation of the switch arm 1, the solenoidy 13 is energized and the core 14 pulled to the left, and the toggles operated to open the switch 1. During-this movement, the conductors 38 and 39r close the branch 30and open or break the branch 31, respectively.

What I claim is 1. An automatic switch comprising a movable switch member, two `solenoids arranged in axial alinement and fdesigned to be` alternately energized, a core common to bothsolenoids and arranged to be acted on in opposite directions by the solenoids, means -for transmitting the movement of the core to the switch member including a toggle, the joint of which is movable into the dead center line of the toggle, a rod connecting the core and the toggle, the rod having a head thereon, and a core located within one solenoid and arranged to be actuated thereby to strike the head and move the rod to shift the toggle to carry the joint thereof out of the dead center line of the toggle, substantially as and for the purpose set forth..

2. An automatic switch comprising amovable switch member, two solenoids arranged in aXial alinement and designed to be alternately energized, a core common to both solenoids and arranged to be acted on in opposite directions by the solenoids, means for transmitting the movement of the core to the switch member including a toggle, the joint of which is movable into the dead center line of the toggle, a rod connecting the core and the toggle, the rod having a head thereon, the rod being connected to one of the links of the toggle by a pin-and-slot connection, and a core located within one solenoid .and arranged to be actuated thereby to strike the head and move the rod to shift the toggle to carry the joint thereof out of the dead center line of the toggle, substantially as and for the purpose described.

3. An automatic switch comprising a movable switch member, two solenoids arranged in axial alinement and designed to be alternately energized, a core common to both solenoids and movable thereby in opposite directions, means for transmitting the movement of the core to the member including a -pair of toggles located beyond opposite ends of the core, the joints of the toggles being movable into the dead center lines of the toggles, and a rod upon which the core is mounted, connected to the toggles, a core located Within one of the solenoids and slidable on the rod, and a head mounted on the rod and fixed thereto and arranged to receive the impact of the sliding core to move the joints of the toggles out of the dead center lines of the toggles, substantially as and for the purpose set forth.

In testimony whereof, I have hereunto signed my name in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State of New York, this 26th day of November, 1913.
